The commenter proposes that EMFs could affect health through microbial and fungal responses, metabolites …

One major gap in EMF research is that we keep asking what electromagnetic frequencies do to human cells while largely ignoring what they may do to the microbes living inside the human body. Humans are not biologically sterile. We carry complex communities of bacteria, fungi, viruses & other microorganisms throughout the gut, lungs, mouth, skin & other tissues. These organisms influence immune function, inflammation, metabolism, neurotransmitter activity, barrier integrity & overall biological stability. If electromagnetic exposure can alter microbial growth, metabolism, oxidative stress responses, gene expression, biofilm behavior or fungal activity, then EMFs may affect human health indirectly as well as directly. That creates a much larger biological pathway: EMF exposure → microbial stress response → altered microbial metabolism & behavior → altered metabolites, inflammatory signaling & oxidative stress → immune dysregulation, neurological effects & systemic illness. This may be especially important with fungi because fungi respond dynamically to environmental stress & are capable of producing powerful secondary metabolites, including mycotoxins. Research should examine whether chronic RF/EMF exposure can influence fungal growth, sporulation, biofilm formation, virulence or secondary metabolite production both inside the human body & within water-damaged indoor environments. The human body should therefore be studied as a complete biological ecosystem, not as isolated human cells. We may actually be looking at two systems being exposed simultaneously: the human host & the microbial ecosystem living within that host. Those systems continuously interact. A relatively weak environmental signal would not necessarily need to directly destroy human tissue to create a substantial biological effect if that signal changes the behavior of organisms capable of replication, communication, biofilm formation & chemical production. This is why HHS should investigate the intersection of bioelectromagnetics, microbiology, mycology, mycotoxicology, neuroscience, immunology & microbiome science. The question should no longer be only: “What do electromagnetic fields do to human cells?” We also need to ask: “What do electromagnetic fields do to the microorganisms living inside us, & what do those microorganisms then do to the human body?” Until that interaction is properly investigated, we may be studying only half of the biological picture.
